The method comprises: obtaining a received signal, wherein the received signal comprises a phase noise signal; establishing a likelihood probability ratio integral model on the basis of the received signal and a preset phase noise parameter, wherein the phase noise parameter represents the phase noise signal and is a random variable; performing phase rotation angle extraction and transformation processing and discretization processing on the likelihood probability ratio integral model to obtain a likelihood probability ratio discrete model, wherein the phase rotation angle represents the phase rotation angle obtained on the basis of the phase noise signal; and determining a likelihood probability ratio corresponding to the received signal on the basis of the likelihood probability ratio discrete model to obtain a demodulation result. In this way, a base station overcomes phase noise, and improves signal receiving performance, signal demodulation efficiency and signal demodulation accuracy by performing phase compensation and discrete calculation on a received signal to obtain the demodulation result."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for demodulating signal","description":"Disclosed are a method and apparatus for demodulating a signal.
